Step-by-step explanation:
product means to multiply, hence the product of 12 and k is
12 × k = 12k ( this is 84 means equal to 84 ), that is
12k = 84 ( divide both sides by 12 )
k = 7 ← is the solution
<span>going downstream -
t = 14/(2 + v)
going upstream -
t = 7/(2 - v)
14/(2 + v) = 7/(2 - v)
(2 + v)/2 = 2 - v
v = 2/3km/h</span><span>
